LOL...does the PFc have a pre-set for 444cc injectors, If you need some numbers for the base tune then i can help you out with some of the numbers from my PFC.

Depending on the turbo you are running our numbers will most likeyl start to differ after 1600rpm.

I'm half way there.Rb20det injectors are out GTR ones in and now need to mod the plugs or get new ones,wire in the resister pack and get it tuned.I've been taking pics for you ChrisR32 to.

do you happen to have pics of the mod'd clip to fit the 13b injectors? Thanks

Its easy to mod the actual injector to be able to take the standard RB20 plug.

The only reason the RB20 plug wont go on is there is a small plastic protrusion in the Inj. socket.

This small lug just needs to be cut away with a stanley knife to make the std plug fit on OK - a fairly quick and easy fix. :)

Roy I have a series 1 RB20DET.The GTR injectors fit the RB20det rail perfect but if you look at the pic the bottom lug on the GTR injectors are off-set more and also has a lug on the inside.I was told they would need modding.

Great stuff, look forward to the end result!

Some pics are not that good.It's straight forward once the plenum is off and some tape is peeled off the injector loom.On the GTR injectors I cut off the bottom lug and the lug it where the plug clips(See pics)

I'll have a daigram up soon,thanks Roy :D

It idles and revs fine with the standard ecu but with the PFC it's very very rich and when ever I drive it I gotta put the injector value to about 650,thats still rich but this friday it's booked in to get tuned.

It was a pretty crude picture, but hopefully it helped. Good to see you had no probs installing them...can i ask where you scored your resistor pack from. If we RB20 owners can get a handle on a readily available supply of resistor packs then we are in business as far as cheap injector upgrades go.

Roy,

I have read up on the message you sent me a while back, and have had a good look at the picks, cheers R31 POWER!

Does anyone else have any other pics or info that would help? What colour is the power wire going to the injector plug?

I have a spare RB20 at home with the injector loom and injectors/rail etc still on it, I might have a go at installing the resistor pack on the spare motor and just swap the whole rail and wiring onto my current motor. Do you guys think this is feasable?

BTW - got my injector pack from Mark Tilbrook, spoke to him at a dyno day the other week, he told me if it works, make him a offer, so at the moment it hasn't cost me a cent :cheers: He was keen to see how it goes

Also, does anyone have a map for there PFC to suit GTR injectors yet?

Chris

It would be more agro isntsalling the new harness then it would be too solder in the resistor pack into your existing engine/harness

As for colours, i cant remember, if R31 POWER cant help you out with colours then i should be able to have a sticky at mien next week and tell you. When are you planning on doing it...anyway you dont really need to kn wo the colour, you can identify it by the way they are wired.

As for a PFC map, buy my TD06 and YES i do :cheers: ...otherwise i can help you out with some base parameters to get the thing to idle and run at low rpm, but i suggest you just get the car to a workshop ASAP...The PFC may even have a rough default settin for GTR injectors?!?! I havent had my PFc that long i cant remember :Oops:

That would be cool. I will try and have a look at the spare motor tonight and see what i can work out, if anyone knows that would be cool.

I bit of a base map for low rpm stuff would be cool, chances are I think my PFC is setup for bigger injectors judging by the numbers that are programmed into the fuel map, either way it will be re-tuned to suit, but it would be handy to drive it rather than tow it to the workshop!

Will be looking at doing it by the end of the month hopefully, whenever I can get some time off........:cheers:

Did you guys use the RB20 O-rings or the ones on the original injectors, or did you get new ones?

Bloody good thread this for RB20 owners looking at injector upgrades!!!!! Roy and R31, give yourself a pat on the back!

Id rather Ms Universe bat me off:thumbsup: . I had my injectors cleaned and flow tested, and at the same time new pintle caps and o-rings were supplied

Shit I was going to write what coulor the wires were but though they would be different.

I can't take credit coz it's all Roy,if it was'nt for his diagram he sent I would'nt have GTR injectors in.

I used all GTR stuff like o-rings and those rubber top bits coz all were new not so long ago.

Chris when you do put GTR inj's in there's a injector harness that unplugs from a plug at the front.It powers the 3 rear injectors and that air motor thingy.We cut the 2 wires going to that motor thingy and used them for the injectors.Read futher.

It's hard to explain but the power feed to the injectors go like this.The main power wire then branches to 4 wires and then 2 wires on that un-pluggable injector harness.So instead of running 2 new wires to those in jectors we used those air motor wires.Plus that plug could be used and it still looks factory.And those 2 wires from that air motor we joined to the same wires that are straight above it in the loom,god knows why nissan did'nt do that before LOL

I think I might of confused you Chris and if so tell me what bits you don't get.

I think I have got the general Idea now - correct me if i am wrong

Wire in the power wire for the resistor pack before it branches off into seperate wires. Connect the seperate wires of the resistor pack with the power wire going to each injector

Is this correct? Do you ahve to run new wires from the resistor pack to the injectors or will the old wire be ok

    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
